BEARING FOR VERTICAL.. SHAFTS.

SPECIFICATION forming part of Letters Patent No. 600,816, dated March15, 1898.

Application filed December 16, 1897. Serial No. 662,193. (No model.)

To all whom it may con/cern:

Be it known that I, J Essa WARRINGTON, a citizen of the United States,residing at In-l dianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvementsin Bearingsfor Vertical Shafts, of which the following is a specification.

The object of my present invention is to provide a suitable singlebearing for vertical shafts of that class generally known asstep-bearings, which may be easily adjusted to bear properly upon theshaft at all times and take up all looseness resultant from wear.

A bearing embodying my said invention will be first fully described, andthe novel features thereof then pointed out in the claims.

Referring to the accompanying drawings,

which are made a part hereof and on which similar letters of referenceindicate similar parts, Figure l is a top or plan view of a bearingembodying my said invention, the shaft carried thereby being shown insection and all parts carried by said shaftserving to cover or conceal,the bearing itself being removed; Fig. 2, a central vertical sectionalView of the same as seen from the dotted line 2 2 in Fig. l, thebearing-cover and a form of pulley carried by the shaft being shown inaddition to the parts shown in said Fig. l; Fig. 3, a detail horizontalsectional view as seen from the dotted line 3 3 in Fig. 2, and Fig. 4 adetail vertical sectional view as seen from the dotted line 4 l in Fig.3.

' In said drawings the portions marked A represent the outer shell ormain chamber of the bearing structure; B B and O, bearingplates withinsaid chamber; D, an adjustingrod, whereby the adjustment of thebearingplates is effected, and E a shaft carried by said bearing.

The outer shell or casing A is substantially in the form of an uprightcylinder and preferably has an enlargement on one side at A', (the formof which is best shown in Fig. 3,) although it might be made cylindricalby enlarging it somewhat. The form shown is preferred, however, as it isthus of less size and weight for the required capacity. This shell issuitably mounted on an appropriate foundation, and I have providedspider-like arms Awhich may extend out a considerable distance, and thusgive a very firm and substantial bearing, besides y providing at theouter ends of said arms means for adjustment,

whereby the shaft may be always kept in an exactly vertical position.There are three of the bearingplates,and consequently this shell may beconsidered as divided into thirds, each third equipped to receive andsupport one 1of said plates. At suitable points in the interior on twoof the threedivisions as thus considered are bearing-ribs a, thebearingfaces whereof are segments of circles of less radius than theshell itself, the form of these being best indicated in Fig. 3. Withinthe bottom I prefer to form an annular rim a to receive and support thebearing-plates. Centrally within this rim and Within a suitabledepression in the interior surface of the shell I place a bearing-platea2 of suitable metal to receive the end thrust of the shaft E and supVaport the weight of said shaft and its load.

Lug's c are formed in the interior of the shell to guide and hold toproper position the bearing-plate C, as is best shown in Fig. l.'

Of the three bearing-plates two, B E, are provided with suitableprojections which fit against the concave surfaces of the ribs a, asbest shown in Figs. 3 and 4. This peculiar formation and arrangementpermits the bear-- ing-plates to adjust themselves circumferentially tobear properly against the shaft and insures that the contact between thebearingsurfaces shall always be uniform. These two bearing-plates havetwo bearing-points each, as shown, whereby they are maintained in fixedsituation so far as their vertical arrangement is concerned.

The bearing-plateO, as shown in the drawings, is of a somewhat differentexterior formation from the bearing-plates B and does not come incontact with the interior surface of the shell A, except at the lowerend, where it rests on the annular rim a', and at points on the sides,Where it is guidingly held by the lugs c. It has a centraltransverseenlargement with which the end of the adj usting-rod Dy comesin contact, as will be presently described. The other bearing-platesbeing supported at or near the ends and this bearingplate beingsupported at or near its center,

proper contact of the said bearing-plates throughout their length withthe shaft is secured. Truss-like strengthening-ribs r on the back ofthis bearing-plate keep it from springing, so that there shall be nobinding of the parts for` lack of stiffness.

The adjusting-rod D is mounted in a suitable screw-threaded extension e,secured to the side of the shell A, and its inner end comes in contactwith the bearing-plate C. As the bearing is intended to be continuouslylled with oil, this adjusting-rod is shown as passing through astuffing-box, by which any escape of oil is prevented. It is providedwith a lock-nut d, by which it can be locked in adj usted position. Saidnut also holds the gland g of the stuffing-box to the proper position toinsure the desired compression of the stung material.

The shaft E is of a common form and is mounted in the bearingsdescribed. It is shown only for purposes of illustration. Only afragment thereof is shown in Fig. 2, the upper end, which carries orconnects with the mechanism to be driven, being broken away, asunnecessary to illustrate in this case, and the lower end being alsobroken out to show the interior of the bearing-plates. As shown in saidfigure, the bearing-plates are lined or babbitted at the ends only, thusleaving the central portion free from contact with the shaft. This isbecause that in a bearing of this length it is unnecessary that thecontactsurface should be continuous. I have shown in Fig. 2 a pulley P,mounted on this shaft E, of a construction iu which the center of thepull of the driving-belt is below the upper end of the bearing, which isobviously desirable in a machine of this character where the shaft hasno support at the upper end. In said figure also I show a cover-plate p,which I have provided, the upper surface of which is somewhat funnel orhopper like and which is intended to exclude the admission of any eX-traneous matter to the interior of the bearing structure shown and alsoto catch and convey into the bearing any oil which may drip from themachinery above.

Having thus fully described my said invention, what I claim as new, anddesire to secure l by Letters Patent, is-

1. The combination, in a bearing for an upright shaft, of the outershell, three bearingplates within said shell, two of which are supportedthereby at or near the ends, and an adj usting-rod whereby the third issupported at or near its center.

2. The combination, in a bearing for an upright shaft, of an outer shelldesigned to contain three bearing-plates, ribs upon two interior sidesof said shell at or near the upper and lower ends thereof and havingconcave surfaces of smaller radius than that of the shell itself, threebearing-plates positioned Within said shell, two of which have convexprotuberances thereon adapted to fit the concave surfaces on said ribs,and an adjustingrod adapted to support the third plate at a point at ornear its center.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 4th day of December, A. D. 1897.
